More routines for operating on iterables, beyond itertools
Project description
I love itertools; it’s one of the most beautiful, composable standard libs. Whenever I have an iteration problem, there’s almost always an itertools routine that fits it perfectly. Sometimes, however, neither itertools nor the recipes included in its docs do quite what I need.
Here I’ve collected several routines I’ve reached for but not found. Since they are deceptively tricky to get right, I’ve wrapped them up into a library. We’ve also included implementations of the recipes from the itertools documentation. Enjoy! Any additions are welcome; just file a pull request.

Version History
- 2.3
Added one from jaraco.util.itertools. (Thanks, jaraco!)
Added distinct_permutations and unique_to_each. (contributed by bbayles)
Added windowed. (Contributed by bbayles, with thanks to buchanae, jaraco, and abarnert)
Simplified the implementation of chunked. (Thanks, nvie!)
Python 3.5 is now supported. Python 2.6 is no longer supported.
Python 3 is now supported directly; there is no 2to3 step.
- 2.2
Added iterate and with_iter. (Thanks, abarnert!)
- 2.1
Added (tested!) implementations of the recipes from the itertools documentation. (Thanks, Chris Lonnen!)
Added ilen. (Thanks for the inspiration, Matt Basta!)
- 2.0
chunked now returns lists rather than tuples. After all, they’re homogeneous. This slightly backward-incompatible change is the reason for the major version bump.
Added @consumer.
Improved test machinery.
- 1.1
Added first function.
Added Python 3 support.
Added a default arg to peekable.peek().
Noted how to easily test whether a peekable iterator is exhausted.
Rewrote documentation.
- 1.0
Initial release, with collate, peekable, and chunked. Could really use better docs.
